Looks like a bug either in EB or datawedge.
Please create a support ticket with the information.
Another workaround is, dom inject Eb.barcode.enable in your application? This will use EB barcode APIs instead of Datwedge scanning.
Thank you! I had originally thought about needing to do something like that, but I was never able to find documentation on it. I do have a case opened with Zebra and I will be glad to update this when or if we find a solution.
